Documentation for individual data value

Behind the Vision of Britain web site is a true data
library, a collection of individual statistics each
with its own metadata to tell users what it means.
These metadata also control how the system visualises statistical
data through graphs and maps.
This is what we know about the particular data value you selected:

Attribute

Value

Meaning

Identifier

34398912

This number locates the particular value within the data table;
it is like an accession number in a conventional library.

Value

33

This is the data value itself.

Date(s) covered

January 1st, 1940 to
December 31st, 1940

We store dates within a date object, which can
hold anything from a simple year value, for a census, to
a period defined by two calendar dates.

This is the name of our script which inserted this data value into
the main data table.
For non-derived values, this is usually done by copying data
values across from our more conventional
GBHDB database, and the scripts are usually
named after the table in GBHDB they copy data from.

This table lists, in its "value" column, a single row from
our data table.
The values are mostly identifiers and codes which are given meaning
by our main sub-systems, and the "meaning" column reaches into these
to tell you more.
